The 3" Lithe Audio passive spot ceiling speaker features a frameless design with grill that magnetically attaches and only protrudes 3mm from the ceiling Featuring a kevlar woven woofer cone, the strength of Kevlar helps the cone retain its shape at very high energy levels and its low mass assures quick, accurate response. The cone's woven surface delivers smooth, uncoloured mids. The high quality rubber surround ensure that these woofers will provide years of consistent, reliable performance. You can even spray paint the grille to create a virtually invisible look that will match any decor. With an impedance of 8 ohms these speakers can be doubled up for two pairs on most standard amplifiers.
